@hjkl.space, @mirohaller.bsky.social, @laurahetz.bsky.social, Matilda and I are organizing CAW this year! Fun fact: a few talks that appeared at RWC this year have also been presented at CAW in prior years. Good track record! 10th May 2026, Rome caw.cryptanalysis.fun

Just finished presenting this work at Real World Crypto in Taipei :) TL;DR: We found 2 attacks on Signal (Android, Desktop) where a malicious server can inject messages in conversations. Super fun project! Thanks a bunch to Noemi Terzo, @kennyog.bsky.social, and @cryptojedi.bsky.social

The call for talks for CAW 2026 (a workshop affiliated with Eurocrypt) is out! This year's motto is "cryptography under real-world constraints and threat models", but other applied cryptography is also very welcome. All info is on: caw.cryptanalysis.fun.

For all the people working under the umbrella term of "Real-World Cryptography": you can't miss CAW 2026! Call for Talks is out now :)

Congrats to @KhanhCrypto (who's not on bsky) for the IACR Grammy Award at #Eurocrypt 🥳 Guess I need to pick up the slack, see you at the next rump session! 😉
